FIELD

This invention relates to a backpack system and more particularly relates to a backpack system with interchangeable elements.

BACKGROUND

Backpacks and other carrying implements are advantageous for providing capacity for cargo such as sporting or work supplies or materials. In many conventional backpack systems, the measure of the backpack is the volume capacity. For example, a daypack may fall in the range of 10-40 liters of capacity while a weekend bag may carry 35-50 liters and an extended trip bag carrying 70+ liters. Therefore, depending on the activity, different bags are better or worse suited and multiple different bags are needed for those who participate in different activities.
